Why It Matters
JavaScript is causing 188ms of forced reflows, blocking the main thread and increasing Total Blocking Time.
How to Fix
Defer jQuery and Elementor JavaScript to load after critical content. Use WP Asset CleanUp to remove unused scripts from non-essential pages. Move DOM queries outside of animation loops in custom JavaScript.

AI Performance Analysis
This WordPress site has poor performance with a score of 54/100, primarily due to an extremely slow Largest Contentful Paint of 21.2 seconds. The biggest culprit is a 3.6MB video file that lacks proper caching and takes forever to load, combined with oversized PNG images that could be 2.5MB smaller if converted to modern formats like WebP. The site is also weighed down by 265KB of unused JavaScript from Google Tag Manager and Facebook tracking scripts, plus 111KB of unused CSS that's unnecessarily slowing down the initial page load. Fixing the video caching, optimizing images to modern formats, and removing unused code could easily improve the performance score by 30+ points and dramatically enhance user experience.
Other Optimization Recommendations
Optimize Images to WebP Format
High Impact+18 points estimatedWhy It Matters:
Large PNG images are consuming 2.5MB and delaying LCP by 550ms, accounting for most of your page weight.
How to Fix:
Install ShortPixel or Imagify WordPress plugin to automatically convert images to WebP format. Enable responsive images in your theme settings. Add explicit width/height attributes to prevent layout shifts during image loading.
Implement Aggressive Browser Caching
High Impact+15 points estimatedWhy It Matters:
Resources totaling 4.5MB have no cache headers, forcing users to re-download everything on repeat visits.
How to Fix:
Install WP Rocket or W3 Total Cache plugin. Set cache expiry to 1 year for static assets (images, CSS, JS). Configure your CDN or hosting provider to add proper cache-control headers for video files and fonts.
